Automated Catch Marketplace Stock-Out Alerts

Every morning, WebRun opens the Catch Marketplace seller portal, checks stock levels and buy box status for every active listing, saves a dated report to Drive noting anything that lost the buy box, and sends an urgent text for any listing that is out of stock while still receiving orders.

In short

How do I get alerted when Catch Marketplace stock runs out?

WebRun checks the Catch Marketplace seller portal every morning for stock levels and buy box status on every active listing, saves a dated report to Drive, and sends an urgent text for any listing that is out of stock while still receiving orders. This catches a costly stock-out the same day it happens.

  • Stock-outs get an urgent text the same day they happen
  • Buy box changes are tracked in a dated report for reference
  • Only genuine stock-outs trigger a text, not routine low stock

Questions, answered

Will it restock inventory or adjust pricing automatically?

No. WebRun only reads stock and buy box status and reports them. Restocking and pricing decisions stay with the seller on Catch Marketplace.

What counts as a genuine stock-out?

A listing showing zero available stock while the seller portal still shows it receiving orders, which is exactly the situation worth an urgent text.

How does it track buy box loss?

It compares buy box status against the prior check and notes any listing that changed, saved in the dated Drive report for reference.
